Eurasia: The Conquest of the East - Season 1 Episode 5 The Caravaneers of the Silk Road (2003)
Chinese Empire. After a perilous trek of some 11 000 kilometres across steppes, mountains and deserts, the caravans entered China through the Jade Gate. For seven hundred years, one particular tribe of caravaneers, the Sogdians, held the monopoly of crossing these hostile regions and became masters in the art of organising and leading caravans between East and West. They were among the best merchants the Silk Road had ever known.
